CC20-G
Operation
Prior to Serial Number C7243MS
The model CC20-G is a combination steamer-oven with a stainless steel cooking
chamber, a steam generator, and electronic circuitry for controlling unit operation.
This gas oven operates from a 115 volt, single-phase, 60 hertz, 15 ampere power
source. The gas supply can be natural gas or propane gas. Supply pressure must
be in accordance with the specifications outlined earlier in this section.
It can function as a convection oven, a self-contained pressureless steamer, or as
a combination oven-steamer. Mode of operation is controlled by the control panel
touch pad switches. A special blower provides high speed forced convection in the
cooking chamber during convection and combo modes.
The gas burners and fan blower operate to provide oven temperatures up to a
maximum of 575°F.
This oven has a gas fired steam generator to generate steam. The steam
generator cavities are adjacent to the cooking compartment. All of the condensate
leaves the oven through the cavity drain. When the unit is turned off, or the oven
cooking mode is selected, the steam generator cavity automatically drains.
The control panel is a solid-state controller. The solid-state circuitry has a self-
diagnostic program to assist you in troubleshooting, and a pre-programmed
cleaning cycle to assist the operator in daily cleaning.
The door interlock switch operates to turn off the fan and shut down the oven gas
burners when the door is opened.
The electrical circuits that are active for the three operating modes are shown in
the following illustrations.
